Snapcraft fails in Docker container when started by Jenkins - docker

Question

I'm trying to build a Snap package in Docker as a Jenkins stage (it just runs the build script) but I end up with this:
Sorry, Snapcraft ran into an error when trying to running through its
lifecycle that generated the following traceback:
Traceback (most recent call last):

mkdir(name, mode)
PermissionError: [Errno 13] Permission denied: '/.local'
So: PermissionError: [Errno 13] Permission denied: '/.local'
Now the thing I don't understand is that if I run my build script manually it works:
CMD="export LANG=en_US.UTF-8 && \
export LC_ALL=en_US.UTF-8 && \
cd /heimer/packaging/snap && \
snapcraft"
docker run --privileged -t -v $(pwd):/heimer juzzlin/qt5:16.04 bash -c "${CMD}"
This is how I run it in Jenkinsfile:
stage('Snap package / Ubuntu 16.04') {
agent {
docker {
image 'juzzlin/qt5:16.04'
args '--privileged -t -v $WORKSPACE:/heimer'
}
}
steps {
sh "./scripts/buildSnap.sh"
}
post {
always {
archiveArtifacts artifacts: 'packaging/snap/*.snap', fingerprint: true
}
}
}
What is the difference? Why does this fail when Jenkins runs it?
